Abstract: A process for obtaining hepatitis-safe, sterile, pyrogen- and stroma-free hemoglobin solutions of low potassium content comprising stirring an erythrocyte concentrate with about 1 to 6-times its volume of an about 5 to 15% aqueous solution of a sugar, sugar alcohol or high-molecular-weight colloid, adjusting the pH of the resulting suspension to about 5 to 6.5 with an acid which is physiologically tolerable as salt, allowing the erythrocytes to settle, removing the supernatant from the sediments, adjusting the pH of the sediment to about 7 to 8, homogenizing the sediment, adjusting its hematocrit to about 55 to 60%, treating the mass with a dilute beta-propiolactone solution, hemolyzing the residual solids and forming a suspension thereof, contacting the suspension with a cation exchanger in H+ form until the pH has decreased to about 5 to 5.5 thereby to precipitate the stroma, separating from the liquid the cation exchanger and precipitated stroma, and adjusting the pH to about 7.2 to 7.6.

Abstract: A corona charging device including a dielectric-coated elongate conductor (11) contacting or closely spaced from a control electrode. In the first version of this device, the control electrode comprises a conductive grid (17), which is mounted against an insulating support (15). In a second version, the control electrode consists of a slotted conductor (94), with the dielectric-coated elongate conductor (11) embedded in the slot (96). A high voltage varying potential (25) between the elongate conductor (11) and control electrode induces a glow discharge in an air region in proximity to the two conductors. The control electrode may act as a grounding member to provide a corona discharge device with respect to a proximate surface (20). Alternatively, the control electrode may be maintained at a desired potential (27) to provide a charging device with an automatically limited voltage. The corona charging devices of the invention are characterized by a linear relationship between output ion currents and a direct current extraction potential. In further versions of the second corona device, the slotted conductor and dielectric-coated conductor may be replaced with alternative structures which provide an equivalent enclosure.

Abstract: The transit exchange has a signal-controlled oscillator with an output signal which depends on the collectively weighted phase difference between the local exchange clock and the clock of the other exchanges. To avoid phase jumps, a signal corresponding to the phase difference is sampled, the sampled values differentiated, the differentiated values compared with a limit value employing a phase jump when exceeded, and when this value is exceeded a signal with the control signal's highest value but with opposite sign is added to form a compensation signal, this compensation signal being added to the differentiated value, and after possible weighting the differentiated value is summed with corresponding differentiated values from comparison with the phases of other links, and the sum value integrated to obtain a resulting control signal.

Abstract: The invention provides method and apparatus for imparting visual surface effects to a relatively moving, thermally modifiable substrate (12) by application of discrete streams of heated pressurised fluid, e.g. gas, to surface areas of the substrate. The apparatus includes an elongate manifold assembly (30) comprising two gas receiving compartments, (81, 160), each extending across the path of said substrate. Heated gas from the first compartment passes into the second compartment, which is comprised of a series of chambers (162, 166) with an elongate exit slot (115) positioned closely adjacent the substrate surface. The gas is uniformly mixed within the second compartment, and may then be directed from the exit slot onto the substrate as a thin, continuous stream or curtain extending the length of the manifold. By use of blocking streams of relatively cool gas which deflect the dilute selected lateral segments of the heated gas stream in accordance with pattern information after the curtain of heated gas emerges from the exit slot, smaller streams of groups of streams may be formed which squarely impinge on the substrate surface and impart a selected pattern to the substrate, by thermal modification of the surface.

Title: Method for correcting time base fluctuations in a reproduced video signal
IPC: H04N9/89
Filed: 1985-09-10
Granted: 1990-09-05
Abstract: Whenever component signals (color difference signals) of a video tape recorder signal are recorded in a recording medium in accordance with timeplex (time division multiplex) method, velocity error inevitably occurs because there always exists a difference in relative velocity between a tape head and tape between recording process and reproducing process. To perfectly eliminate the velocity errors included in the component signals when reading out the signals, a first read clock signal (RCKR) is generated to read a first component signal recorded in the first half of each horizontal period segment under consideration of integral velocity error as in the conventional method, but a second read clock signal (RCKB) is generated to read a second component signal recorded in the second half of each horizontal period segment under consideration of both initial offset velocity error and integral velocity error.

Abstract: In producing hollow bodies by blow molding from thermoplastic material, a preferably tubular preform is firstly formed, and is then expanded within the blowing mold under the effect of an inert gas under high pressure, until it bears entirely against the inside surface of the blowing mold. Thereafter, a reaction gas such as fluorine is introduced into the hollow body under a considerably lower pressure, while the hollow body is still in the mold, to treat the internal surface of the hollow body to render it impervious to gas and/or liquid. After the reaction has elapsed, a flushing and cooling gas is introduced into the hollow body and is then removed from the blowing mold after the hollow body has sufficiently set.
